ssh connections being dropped

[Gabriel Gunderson]

Has anyone seen this before?  After about 10 mins (or so) my shh 
connection will be dropped.  It's only on one of many remote servers 
that I connected to.  I don't believe it's on my (client) side.  This 
particular server is running openssh-server-3.9p1-8.RHEL4.9  Logs show 
nothing.  Google yields nothing to my untrained eyes.  Possibly relevant 
info below.  Any ideas where to start on this one?
